Sure! Here's a simple implementation of the game you described using HTML, JavaScript, and pictograms for smartphone operation. Just copy and save the code as a single HTML file (e.g., "game.html") and open it in a web browser to play.
In this game, you can tap/click on the screen to build new buildings on the planet. The buildings and workers will be generated randomly. At night (when the game is off), the workers will be visible on the planet. You can zoom out to the world map and destroy the planet by pressing the "Zoom out" button.
Note: This is a basic implementation that demonstrates the concept you described. You can modify and expand upon it to add more features, interactions, and graphics as per your requirements.
